Rhyolite lava flow (Puyehue-Cordón Caulle, 2013)

The dark material is the front of a lava lobe from the 2011-2013 eruption, as it encroached on a nearby ash-covered ridge (the light coloured material). The flow is several tens of metres thick, with an irregular surface comprising massive blocks of lava. The point cloud shown is a small section of a larger reconstruction that covers several kilometers of the flow.
